Using knives in cast iron pans

I have a fairly recent 12" Lodge cast iron pan that I use weekly to make pizza in.
I cut it in pieces directly in the pan; last week I realized that the knife left slight etched marks on the finish (yeah i just realized the idiocy of it all...)

(Metal spoons/other tools don't leave marks - and i'm pretty brutal with my cookware - so what gives?

Obviously this should affect the seasoning. So should I just remove the whole pizza out of the pan before slicing or is there some kind of knife/contraption I could use that won't scratch the pan?

  1. We are talking about the traditional bare cast iron Lodge pan, right? Don't worry about the marks. Seasoning will generate over time. You scrap some, you generate some. Unless, you only use that pan for pizza and cut it with a knife every single time, I don't think it is a big deal.

    However, to answer your question specifically, you can always use a plastic knife. I use a plastic knife on my Teflon nonstick bakeware.

      Yeah the preseasoned ones, not enameled or anything... I use it for everything from roast chicken to bacon etc. I'll stop worrying.
      Thanks for the tip about plastic knives, didn't even know such a thing existed.

    2. Forget the pan, think about what you're doing to the knife! Just pop it out of the pan onto a cutting board and hit it with a pizza wheel, no damage to anything that way.

        Lol, now I feel double-foolish... thanks, that sounds pretty sensible .
        (I do use a pizza wheel and not a knife, couldn't find the right term for it - not a native english speaker...)

      2. I agree with Mikie -- just move the pizza to a cutting board, as I always do with my pizzas (cooked on a stone, rather than in a pan).

        As for the cast iron, personally I find marks from metal utensils to be rather annoying when they scratch or dig into the seasoning. As Chemicalkinetics said, you will be able to regenerate the seasoning over time, but I personally love my perfectly smooth non-stick surfaces I've generated over the years. I find deep groves from a metal utensil can take months to go away again. I like to be able to slide anything easily around my pan (even omelets and such), so even tiny grooves are a hindrance.
